Purification and properties of the activating enzyme for iron protein of nitrogenase from the photosynthetic bacterium Rhodospirillum rubrum.
The oxygen-labile, activating enzyme for iron protein from the photosynthetic bacterium, Rhodospirillum rubrum, was purified 11,800-fold using a combination of chromatophore washing, DE52-cellulose chromatography, hydroxylapatite chromatography, reactive red-120 cross-linked agarose chromatography, reactive red-120 cross-linked agarose chromatography, and Sephadex G-75 gel filtration. Activatin...
متن کاملPurification and properties of dinitrogenase reductase ADP-ribosyltransferase from the photosynthetic bacterium Rhodospirillum rubrum.
The enzyme that catalyzes the ADP-ribosylation and concomitant inactivation of dinitrogenase reductase in Rhodospirillum rubrum has been purified greater than 19,000-fold to near homogeneity. We propose dinitrogenase reductase ADP-ribosyltransferase (DRAT) as the working name for the enzyme. DRAT activity is stabilized by NaCl and ADP. The enzyme is a monomer with a molecular mass of 30 kDa and...
متن کاملAmino acid sequence of cytochrome c' from the purple photosynthetic bacterium Rhodospirillum rubrum S1.
The amino acid sequence of cytochrome c' from the purple photosynthetic bacterium Rhodospirillum rubrum S1 has been determined and is consistent with homology to cytochrome c' from the nonphotosynthetic bacterium Alcaligenes sp. NCIB 11015. There is 29% identity in the chosen alignment of these two proteins. R. rubrum cytochrome c' is composed of a single peptide chain of 126 amino acid residu...

متن کاملCharacterization of two soluble ferredoxins as distinct from bound iron-sulfur proteins in the photosynthetic bacterium Rhodospirillum rubrum.
In an earlier investigation (Shanmugam, K. T., Buchanan, B. B., and Arnon, D. I. (1972) Biochim. Biophys. Acta 256, 477-486) the extraction of ferredoxin from Rhodospirillum rubrum cells with the aid of a detergent (Triton X-100) and acetone revealed the existence of two types of ferredoxin (I and II) and led to the conclusion that both are membrane-bound. In the present investigation, ferredox...
